History Trivia / SonicAdventure2

* SequelFirst: ''Sonic Adventure 2 Battle'' was released first on the UsefulNotes/NintendoGameCube a year before ''VideoGame/SonicAdventure DX Director's Cut'' was released.

** For most of the game, David Humphrey voices Shadow. But Ryan Drummond took over for a few lines during the FinalBoss due to complications surrounding labor laws. According to [[https://www.youtube.com/watch?v=b7hFchMN19w&t=1830s Ryan Drummond in a panel]], David Humphrey had completed a day's work of voice recording, but Sega realized they had forgotten to have him record some of Shadow's lines. Since he had already left the studio, Sega would have to pay him for another full day if they called him back to the studio. When Ryan showed up to the studio later that day, Sega asked him to impersonate David Humphrey to save money.

** For most of the game, David Humphrey voices Shadow. But Ryan Drummond took over for a few lines during the FinalBoss due to the former being unavailable at that point.

* DevelopmentGag: The "Magic Hands" ability for Sonic is reference to an early concept for ''Sonic 1'' where the main character -- then a rabbit with a bowtie -- would use his ears to trap enemies then throw them at other enemies to defeat them.

* ReferencedBy: In Chapter 2 of ''VideoGame/{{Deltarune}}'', one of Mauswheel's battle quotes reads "(Rolling around at the speed of mouse...)", riffing on the opening line to "Escape from the City".

** For unknown reasons, Meteor Herd contains an invisible grind rail that loops around from the center area and ends near the starting point of the level. Knuckles can't grind and simply passes through it, but the rail can be used like any other rail in the game if Sonic or Shadow is forced to be the player character with cheats or glitches.

** Tails, who was voiced by Corey Bringas in the first game, is now played by Corey's younger brother, Connor. Ditto for his Japanese voice from Kazuki Hayashi-to-Atsuki Murata

* ModelDissonance: By porting the game's cutscenes to ''Sonic Adventure 2: Preview'', and using the debug cutscene viewer, one can find that a lot of characters don't look like they should when the camera is not focused on them. [[https://www.youtube.com/watch?v=dWevkjKgJX4 Such gems include]] Amy missing almost her entire body not once but twice throughout the whole game, Shadow having quite a few derpy eye moments, Sonic's model growing into existence after he uses Chaos Control to get out of the capsule, Eggman's bottom jaw ''expanding into the horizon'' as Rouge introduces herself to him, and many more examples.

* WhatCouldHaveBeen: [[WhatCouldHaveBeen/SonicAdventure2 Has it's own page]]

** While it didn't directly spawn the once-common rumor of a "Sonic and Knuckles RPG", there was some speculation that said (ultimately theoretical) project had been retooled into this game.

* NamesTheSame:
** ''Sonic Adventure 2'' has a level called Sand Ocean, which shares its name with a series of courses from the ''VideoGame/FZero'' franchise. Became HilariousInHindsight when Sega helped Nintendo develop ''F-Zero GX'' a few years later, which led to further deliberate [[ShoutOut Shout-Outs]] to ''F-Zero'' in ''VideoGame/ShadowTheHedgehog''.
** Prison Island. It will definitely ring bells to anyone who played ''VideoGame/XenobladeChronicles1'' before this one and vice versa.

* TalkingToHimself: Ryan Drummond voices Sonic, and also recorded [[https://www.youtube.com/watch?v=6Mc5vUsMT2E additional dialogue]] for Shadow during the FinalBoss.

* RenamedToAvoidAssociation: Likely to avoid potential legal disputes with Soap, The 2012 HD rerelease of the game would rename Sonic's unique soap shoes to the "2G Hi-Speed Shoes".

** For most of the game, David Humphrey voices Shadow, Ryan Drummond took over for a few lines during the FinalBoss due to the former being unavailable at that point.

* GodNeverSaidThat: Rouge is ''not'' a GUN agent in ''Sonic Adventure 2''. [[spoiler:She works for the President of the United Federation and his secretary]]. Rouge wouldn't officially be part of GUN until ''VideoGame/SonicTheHedgehog2006''; even in ''VideoGame/ShadowTheHedgehog'' she's only a "government agent".
